Two official series, not a national coverage percent. ADMIE publishes a daily filling rate for each hydropower entity in its workbook, and a total for that workbook. The file has no storage volume, so none is calculated. A rate above 100% is shown as published. EYDAP publishes cubic metres for Evinos, Marathon, Mornos and Yliki. That feed does not publish a percent full, so this page does not invent one. Irrigation dams outside these two files are not listed.

The bar is the Reservoir Transparency Index coverage score. This page does not count a percent of all Greek reservoirs. It lists the hydropower entities in the ADMIE workbook and the four EYDAP reservoirs. ADMIE publishes a filling rate, not a volume. EYDAP publishes cubic metres, not a percent full.
